本文提出了一种计算铣削加工中防止工件与球头夹具元件之间滑移的最小夹紧力的解析方法。在确定工件与球头夹具元件之间的接触变形后，得到了工件位移与接触变形之间的关系。基于静态平衡方程，将这些方程组合起来，得到了计算工件与球头夹具元件之间切向接触力的线性方程。根据最大切向接触力，计算出防止工件与球头夹具元件之间滑移的最小夹紧力。最后通过一个仿真实例对该方法进行了说明。
This paper presents a analytical method to calculate the minimum clamping force to prevent slippage between the workpiece and spherical-tipped fixture elements during milling process. After the contact deformation between the workpiece and spherical-tipped fixture element is determined, the relationships between the workpiece displacement and the contact deformations are obtained. Based on the static equilibrium equations, these equations are combined and linear equations are obtained to calculate the tangential contact forces between the workpiece and spherical-tipped fixture element. According to the maximum tangential contact force, the minimum clamping force to prevent slippage between the workpiece and spherical-tipped fixture elements is calculated. At last, this method is illustrated with a simulation example.
